| 摘 要： | 对采空区路基路面建立模型,研究了开采宽度和开采厚度对路基变形的影响.研究结果显示,路基的最大沉降量和水平位移随着开采宽度的增大而增大,且增幅较大;路基路面各种位移和变形值随着开采厚度的增大而增大,采空区路基路面位移和变形值的大小与开采厚度正相关.

| Abstract: | Through established road model of mined-out area, the influence of ness of mining on deformation of subgrade is studied. The research result shows the width and the thick- that the maximum settlement and horizontal displacement of subgrade significantly increase with the increase of mining width, subgrade＇s movement and deformation values also increase with the increase of mining thickness, minedout area subgrade and pavement＇s movement and deformation value are positively correlated with mining thickness. |

| Keywords: | two-dimensional analysis model mining width mining thickness subgrade deformation |
